bug in egcs-g++-1.0.2-12

[Reuben Pasquini]

Hello,

I've come across a bug in egcs-g++-1.0.2-12 on my
RedHat 5.1 Linux system.  The problem results when
I try to instantiate an object of a class that
overides the new operator and is a subtype of two classes 
(multiple inheritance) that also both overide new.


I get the following error:

pasquini@joanne 9 tests/PCS/bin % make LP_thread.o

../src/LP_thread.cpp: In method `void LP_thread::run()':
../src/LP_thread.cpp:62: Internal compiler error.
../src/LP_thread.cpp:62: Please submit a full bug report to
`egcs-bugs@cygnus.com'.


Line 62 is:
     op_mesh = new (MapNoGC) PCS_mesh ( i_mesh_dimension, op_rng );

I've attatched the code for LP_thread.cpp, PCS_mesh.hxx,
and PCS_mesh's two supertypes - Batch and State.
The Solaris CC compiler is able to handle this code,
so I assume it's correct.

Thanks for your work on egcs, and good luck.
Reuben
